I have recently bought a 2 row planter that was converted over to be pulled by a tractor, is there any place that i can find out what model number it is and if there is any place i can find an owners manual. It is in excellent condition, just needs a couple of springs and a new pant job. It is a present for my wife since her father was an IH dealer until Case bought them out. Any info would be greatly appreciated. From N.W. Ohio, Thank You.
